Anker SOLIX PS400 Bifacial Portable Solar Panel (400W)

If you're spending extended time off-grid — think longer van life stints or multi-day camps — the PS400 Bifacial gives you the headroom to keep a larger power station topped up. It's over 50% lighter than most panels putting out this much power, so it's still genuinely portable despite the numbers.

Features

• Folds down light and easy to carry — around 9.9kg, so it won't weigh down your kit

• Backed by a 5-year warranty and rated to a 10-year lifespan, with IP68 protection against water and dust — built to handle actual outdoor use, not just backyard weather

• Bifacial design means it's still pulling in power from bounced light off snow, sand or concrete — a genuine bonus in bright, open settings

• N-type solar cells rated 25%+ efficient, so it keeps performing even when things heat up

FAQ

Is it waterproof?
Yes — it's IP68 rated, so light rain and splashes are no problem. Just don't leave it out in a downpour or dunk it underwater.

Why isn't it hitting the rated wattage?
Like any solar panel, real-world output depends on how strong and direct the sunlight is. Cloud cover, a poor angle, or partial shade will all pull the number down — for the best result, give it clear, unobstructed sun.

How do I keep it clean?
A soft cloth handles everyday dust, and a damp cloth will lift any residue off the solar surface. Try not to let dirt build up for too long — it can start to affect performance.

Anything to watch out for?
The metal frame can get properly hot after a few hours in direct sun, so avoid grabbing it bare-handed — gloves are a good idea when you're repositioning it.
